As per IFC binding, Absence of "little-endian" field causes registers
access in big-endian mode.
So no need to set explicit big-endian field IFC node for LS1043A and
LS1046A.

access in big-endian mode.
So no need to set explicit big-endian field IFC node for LS1043A and
LS1046A.

s/filed/flied in subject, and having 'fsl' in subject prefix might be
better, so that it's clear this is a fsl specific changes.

I fixed them up and applied the patch.
